T 0 all whom it may concern:

Be it known that I, MEINHARD H. Ko'rznmm, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in vaporizing-Burners for Hydrocarbon Fuels; and I do hereby de- -clare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is-to provide a simple, inexpensive and effioient vaporizing burner in connection with which may be used hydrocarbon fuels of a more or less crude or unrefined form under conditions conducive to economy in the consumption and cost of the fuel together with completeness of combustion; and with these objects in view, the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the drawin s, whereinigure 1 is a side view of a burner embodying the invention,

Fig. 2 is a top plan View of the same,

Fig. 8 is a vertical longitudinal section on the plane indicated by the line 33 of Fig. 2,

Fig. 4 is a horizontal section on the plane indicated by the line 4-4 of Fig. 3, and

Fig. 5'is a detail section on the plane indicated bythe line 55 of Fig. 3.

The burner consists essentially of a vaporizing retort 10 in the form of a tubular conductor with which communicates the fuel supply pipe 11 having a suitable controlling valve 12, an annular superheating retort 13 for complete longitudinal traverse by the vaporized fuel from the inlet 14 thereof to the outlet 15, a transverse partition 16 being arranged in said superheating retort to insure the'direction of travel indicated by the arrow in Fig. 4c, a burner cap- 17 in the general form of an inverted cup and con- 'structed for example of refractory material or of suitable metal, a mixing tube 18 disposed in an upright position with its upper or discharge end within the burner cap, and a feed tube 19 extending downwardly from the superheating retort and provided with a gas outlet orifice 2O controlled-for example by a needle valve 21.

The vaporizing retort is provided with a filler consisting of a mass of steel wool 22, a mass of gravel 22 and a mass of steel a heating unit in the form of a resistance coil 27 which is also included in the same circuit with the heating coil 23. These heating coils are employed to effect an initial vaporization of the fuel whereby to permit the burner'to be quickly ignited. lVithin a very short time after igniting the burner, the retorts 10 and 13 will have become heated sufiiciently to vaporize the fuel, and when this occurs the switch 26 is opened to break the circuit to the heating units as they need no longer be employed.- These heating units provide an excellent means for producing a rapid initial vaporization of the fuel, and they may be conveniently controlled. The

asbestos jackets surrounding the heating units cause all the heat generated therein to be spent in the vaporization of the fuel.

.The burner cap is arranged within and concentric with the superheating retort and is provided with radial burner slots 1"? through which the mixture of fuelrand air or the like combustion supporting agent is discharged to be ignited exteriorly of the cap, the latter having a substantially cylindrical sidewall and a centrally depressed or cupped upper wall as indicated at 28. The top of the burner is preferably coned downwardly at its inner side to form a spreader 29 located in axial alinement with the mixing tube 18 which is preferably contracted between its lower and upper ends and is belled or expanded terminally as shown clearly in Fig. 3, 'so that while the lower or inlet end thereof serves to provide for the influx of an adequate supply of air to be mixed with the vaporized fuel, the upper end serves to permit of the expansion thereof around the spreading cone 29 to provide for a substantially uniform distribution of the mixing to the periphery of the burner cap.

The superheating retort is base and It will the burner cap and mixing tube are supported by inwardly directed brackets. .32

fromthe upper ends of said standards, as

also shown in Fig. 3, the mixing tube having an exterior sleeve 33 provided with a flange 34 upon which the burner cap rests at'its lower edge. vThe sleeve 33 extends to the .up'per flared edge of the mixing tube and is edges; thereof-,serves to disposesaid retort in the zone of the flame due to the co'mbus tion of the-mixtureexteriorly of the burner cap; while the lowering ofthe temperature of the mixture in the super-heating retort in its vpassage to the burner orifice is prevent ed by thev auxiliary heating apparatus con- 'to control said'valve.

sisting of the electric unit embracing the feed tube 19. The needle valve2l may-be controlled and actuated a suitable op-" erating lever 36, said valve Passing through a suitable stufling; box -37 Having thus described the invention, what I claim 1s:

A liquid fuel'burner constructionincluding a frame having standards, brackets extending from the standards, an annular re- -tort mounted by thestandards, a burner construction surrounded by the retort and mounted by the brackets, a fuelsupply com duit extending frbm the retort' below the burner and having a discharge valve therein, and meansmounted by one ofthestandards- In testimony whereof I in presence of twowitnesses.
